If 3DS allows people to text via Wi-Fi I say YESH! Just like yahoo messenger allows people to text to cell phones. If Nintendo markets it then it has chance.
Then if it markets it like a MP3 player, so people can see they don't necessarily need an ipod for music and for watching 3D movies!
BUT MOST IMPORTANT: It's awesome line up of games!
